- Be
- Ba
- Mg
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Lithium (group 1, period 2) shows a diagonal relationship with an element of group 2 in the next period.
Step 2: Identify
This element is magnesium. The two have similar atomic and ionic sizes and similar polarising power.
Step 3: Conclusion
Magnesium resembles lithium.
Final Answer:
Magnesium resembles lithium. \[ \boxed{\text{(D) }\text{Mg}} \]
